Hydraulic oil temperature is too high what are the effects on the machine

Release time :2017-10-26 10:37:05

Dongguan hydraulic press manufacturer to tell you that affect the oil temperature is too high for the machine will have?

Higher temperature can reduce oil viscosity, leakage probability increases, the volume of hydraulic oil pump efficiency and the efficiency of the whole system will be significantly reduced. As a result of the oil viscosity is reduced, valve and other moving parts of the oil film thinning and cut broken, frictional resistance increases, lead to wear and tear. Thermal deformation and can lead to mechanical parts, hydraulic components in the thermal expansion coefficient of different moving parts due to its smaller fit clearance and stuck, cause action failure, affect the hydraulic system of transmission precision, deterioration in quality parts work. Will also accelerate the oil oxidation and precipitation asphalt material, reduce the service life of hydraulic oil. Precipitates jam the damping hole and slot valve ?
